Quick Summary
The National Institute of Standards and Technology (NIST) is conducting market research through a Sources Sought notice to identify potential sources for a Pfeiffer Vacuum A100 L Pump, Model Number A100L31324. This specific dry multi-stage roots pump is required to replace a broken unit in a dilution refrigerator used for mission-critical ultra-low temperature experiments in metrology for quantum information science and electrical standards dissemination at Gaithersburg, MD. Responses are due by May 15, 2026.
Scope of Work
NIST requires an exact replica of the existing Pfeiffer Vacuum A100 L Pump, Model Number A100L31324, to ensure compatibility, shared footprint, connections, and interchangeability of parts among dilution refrigerator systems. The pump circulates helium mixture gas in a dilution refrigerator, which produces ultra-low temperatures (0.01 K).
